Since it's open source, I would imagine that these features will be added by someone. I wonder if there would be any interest in a browser designed for Free Republic. I would like to have a button that would take me to the FR comments page of an article I'm reading...
I was wondering about that too. A few months ago, I compiled a Cocoa app that could become a Free Republic web browser. It's basically WebKit rendering engine with Apple's user interface.
It's called... wait for it... ... ... the "FRowser".
I had several cool ideas for it, but haven't done anything with it since. With some additional coding, it could do automatic signatures, tagline rotation, blacklisting messages by user-specified screen names, etc.
